Answer:
The volume of figure 1 is 11340 ft^3 greater than figure 2
Step-by-step explanation:
For rectangular prism, volume is
V = lenght x width x height
V = 36 x 21 x 18 = 13608 ft^3
For rectangular pyramid, volume is
V = (lenght x width x height) ÷ 3
V = (36 x 21 x 9) ÷3 = 6804/3 =2268 ft^3
Difference in volume = 11340 ft^3
Answer:
$ 454.86 : $33.25
Step-by-step explanation:
1.
Alex bought the new easy chair for $ 399 .
If she pays the amount in 13th month. So, she has to pay the interest of 1 month too , which is, = $
= $ 55.86
So, total amount she has to pay for the chair,
= (cost price of the chair + interest)
= $ (399 + 55.86)
= $ 454.86 (answer)
2.
If she wants to pay the amount within the 12 months, so that she doesn't have to pay the interest, her budget for that for each month will be ,
$
= $ 33. 25 (answer)
Answer:
The residual value is -1.8 when x = 3
Step-by-step explanation:
We are given the following table
x | y
0 | -3
2 | -1
3 | -1
5 | 5
6 | 6
Residual value:
A residual value basically shows the position of a data point with respect to the line of best fit.
The residual value is calculated as,
Residual value = Observed value - Predicted value
Where observed values are already given in the question and the predicted values are calculated by using the equation of line of best fit.
When we substitute x = 3 in the above equation then we would get the predicted value.
So the predicted value is 0.8
From the given table, the observed value corresponding to x = 3 is -1
So the residual value is,
Residual value = Observed value - Predicted value
Residual value = -1 - 0.8
Residual value = -1.8
Therefore, the residual value is -1.8 when x = 3
Note: A residual value closer to 0 is desired which means that the regression line best fits the data.
